Learn about dilated cardiomyopathy, a stretching of the heart muscle that usually results in the heart being unable to pump effectively.

Key points

  • In dilated cardiomyopathy, the muscle in the heart stretches and increases the size of the ventricular chamber, making it difficult for the heart to pump blood to the body.
  • Familial dilated cardiomyopathy occurs through many generations and accounts for up to 40% of people with this condition.
  • Symptoms for this condition are similar to congestive heart failure and may be difficult to treat.
